The invention discloses a gemel for the door or e window, and includes a first leaf and a second leaf which are connected with each other through shafts. The invention is characterized in that an anti-theft pin is fixed on the first leaf, and an anti-theft hole corresponding to the anti-theft pin is arranged on the second leaf. The invention is characterized in that the structure is simple, the anti-theft pin and the anti-theft hole are respectively arranged on the first leaf and the second leaf of the gemel, when the door or the window is closed, the anti-theft pin matches with the anti-theft hole; and the material of the anti-theft pin is rigid steel, which is more hard and difficult to be sawn break or damaged, and can protect the door or the window from being detached with high safetyand reliability. In addition, the first leaf and the second leaf are connected together through an upper pin shaft and a lower pin shaft which are opposite to each other; the upper pin and the lower pin shaft are hard to be detached with a certain safety function.
Description
technical field [0001] The invention relates to a hinge, in particular to a door and window hinge. Background technique [0002] Many existing doors and windows are basically equipped with hinges. Through the hinge connection, the doors and windows can rotate freely without noise. It has anti-theft function and low safety factor, and the two blades of many hinges are only connected by a pin, so they are relatively easy to be disassembled. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a door and window hinge that is not easy to be dismantled and has good safety performance. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a door and window hinge, including a first leaf and a second leaf that are axially connected to each other, the first leaf is fixed with an anti-theft pin, and the second leaf An anti-theft hole corresponding to the anti-thef...
